I don't know that it's quite as sinister as incentivising products to be actively anti-user friendly.
If you think about it, the only products that are typically supported via contract seem to be extremely sophisticated, large, or cornerstone products. Making such products OneTouch-EZ is likely a waste of everyone's time and resources, because you have to hamstring the product and spend a ton of development effort making it idiot-proof, when you could have just been making it better instead.
You are right, it is not really sinister and I never suggested it was. It is just unfortunate that you cannot go the open source route if you are not within a certain range of products.
